Abstract
Research and/or Engineering Questions/Objective
The ASPECSS project is a collaborative project with the goal to develop harmonized evaluation procedures for integrated pedestrian safety systems (e.g. Autonomous Emergency Braking AEB). These procedures can be used by legislatives and NCAPs (e.g. EuroNCAP) to assess these systems. Main focus of this paper will be test procedures to assess the pre-crash performance of pedestrian AEB systems, but the project does also address crash performance improvements due to these systems as well as human machine interface performance, e.g. regarding warning signals.
Methodology
A test setup to compare the performance of different AEB systems consists of test tools, test scenarios and a procedure defining how the test will be conducted. The ASPECSS project developed and defined different types of test setups for different test scenarios (which in general are in line with other proposed test scenarios but feature a broader range of parameters concerning impact position and pedestrian velocity). Tests with various production and prototype cars have been conducted using these setups and scenarios, and using different combinations of pedestrian dummy and propulsion system.
Results
This paper will present the achieved performances and accuracies (e.g. controllability of the test setup) for the different setups and scenarios as well as test results with a set of different vehicles with prototype as well as serial production pedestrian AEB systems on board. The repeatability and robustness of the test procedure will be analyzed and a recommendation for pedestrian active safety test procedure requirements will be derived.
What does the paper offer that is new in the field including in comparison to other work by the authors?
The paper offers a robust and reproducible test and assessment methodology for preventive pedestrian safety systems based on accident analysis and considering technical limitations, esp. a set of test scenarios. These new scenarios will be extensively re-tested for verification in March 2014.
